Compatibility with OpenSearch 2.16.0

[f-galland]

Description

We need to ensure the compatibility with the next version of OpenSearch v2.16.0
This update is still being discussed, but we need to be aware of potential issues.

For that, we need to:

• Review opensearch's release notes.
• Identify improvements and potential impact.
• Create new development branch.
• Develop a testing environment to verify our components would work under this new build.

Issues

We will reopen this when 2.16 is out. Closing it for the time being.

Better to wait until 4.9.0 is out so we can easily sync the branches.
